SSCJ: A Semi-Stream Cache Join Using a Front-Stage Cache Module

An Efficient Stream-based Join to Process End User Transactions in Real-Time Data Warehousing

In the field of real-time data warehousing semistream processing has become a potential area of research since last one decade. One important operation in semi-stream processing is to join stream data with a slowly changing diskbased master data. A join operator is usually required to implement this operation. This join operator typically works under limited main memory and this memory is gener...

Reduction in Cache Memory Power Consumption based on Replacement Quantity

Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...

Adapting Hash Joins For Modern Processors

Hash join algorithms are crucial to the performance of modern database systems. Conventional hash joins exhibit poor memory system performance on modern processors because their key data structure, the bucket-chain hash table, is ill-suited for the performance characteristics of out-of-order processors with large cache hierarchies. Whereas prior research has considered a variety of optimization...
